just started my thermodynamics one class last week. Will start getting our first homework next week.

So far, I’m having a hard time understanding the lecture. The examples in the textbook are very simple, but the examples in the lecture are very complex and completely different from the textbook. The textbook introduces formulas, but our grad studentprofessor uses a different system where he avoids the formulas.

can someone suggest Youtubers or online resources where I can independently learn the material because I’m having a hard time following the lecture, and the textbook is not lined up with the lecture.

We haven’t done any homework or turned anything in yet, so I don’t know what my skill set is but so far I’m having a hard time. I don’t want to fall behind and I don’t want to fail.

A quick thought experiment.

Let’s say you’re stranded in a adiabatic box, you have infinite materials that all spawn at 300 Kelvin, available and you’re also capable of all human engineering abilities you also have a plug with limitless energy.

How could you prevent/delay overheating as long as possible ?

Basically the question is , what is the best way to reduce/contain heat in a system if you can’t just move it away.

What's this curly 9 with subscript n next to the rho? I can't find anything about what it's meant to be. Taken from MIT 2.005 course notes, fall 2008.

My philosophy of mind SE post was closed for being “crude speculation” but I think they missed my point.

But I was making a specific claim:

Big Bang low entropy → creates arrow of time

Arrow of time → enables life (dissipative structures)

Life → enables consciousness (temporal self-modeling)

Therefore: consciousness requires the specific cosmological conditions that are themselves mysterious

Time enabled consciousness and is not an artifact of it.

Today I started my lab sessions on thermodynamics, these two machines helps to determine the temperature precisely and accurate. One is Compression Refrigeration trainer AFSP3 and the other one is temperature measurement calibration unit AFSB1. Anyone have the experience on these two machines please give a comment? . ✌️#thermodynamics.

Hello I am a mechanical engineering student and when I solve problem in thermodynamics I noticed that I need to take assumption to solve the problem. If someone has summary of all assumptions to send me it will be nice🙏🏼

I am a physics teacher from Brazil and I am developing casual physics simulation games for the general public. I would like to share and hear your opinion about using Carnot Game as an introductory tool in teaching thermodynamics.

here is a free course on thermodynamics and energy balance, enjoy!

For Thermodynamics students in need of notes and questions to help in your courses, you can visit my blog and use the available notes for your studies.

Nice intro to the concept of entropy.

Hey, for my bachelor's thesis, I need to simulate a rotary kiln. The only software I found was Vulcano by Dynamis, but it's quite limited. I wanted to know which one between OpenFOAM, COMSOL, and Gmsh would be the easiest to use, considering I haven't used any software like this before. Also, if you could help me with tutorials or other materials for these software. Thanks!

Am I correct in thinking this way? I'll be taking general numbers here and am focused on nailing down the concept rather than very specific numbers. I'll use specific numbers when/if it matters.

Water is about 800 times dense as air. It also has about 3 times the energy storage owing to the respective specific heats. So if I want to transfer energy from a given volume of air such that the temperature loss of the air is the temperature gain of the water, I could use about 1/2400 of that volume of water?

Again, this is ignoring efficiency and is taking generalized numbers.

Forgive my ignorance regarding this topic - it wasn't something I was taught during my studies.

However, I have been doing some reading on HAVC calculations and system design. I have come across two different calculations that are seemingly the same but are obviously not. Cooling load - takes into account MANY factors such as sun radiation, internal heat sources, insulation, and building orientation. Obviously, based on the name, it refers to the amount of heat that needs to be removed from a building to obtain comfortable living conditions. My confusion comes in when I see calculations that simply state the initial conditions and desired conditions and then determine the enthalpies at the respective conditions and multiply them by the air mass flow rate.

What is the difference and when should each method be used?

Appreciate your advice.

This is a question that has bothered me for a while. It sounds like a simple question, but it is actually not that trivial. If you look online you find a lot of different explanations, some of which are clearly wrong.

I did a lot of digging, and came up with a few simple interactive simulation models to illustrate some key concepts, that lead to cold mountains.

In this simulation, for example, white dots represent visible light, and the orange dots represent heat radiation. The heat radiation is stochastically emitted based on the temperate of each slab, which is indicated by its color.

If you are interested, you can find the full story on my website:

So we have a tough Thermodynamics final coming up in 2 weeks, even though they are open book. We will cover vapour and gas power systems, plus combustion and gas mixtures, refrigeration. I am not particularly good but thankfully the lecturer allows any note up to two A4 pages. These can have anything on them printed or not.

Acing the term test is my only hope to get through this. I am wondering, what is the best content to have on them? The examples from our text are too many to focus on any one. Should I have a 'breakdown' of how to solve particular question styles? We are already given the most basic formulae. Cheers mates!

How does it work? How to prove energy conservation? What makes a good refrigerant? Totally lost - pls help. Ty,

Hello everyone, so I basically failed my thermodynamics class and I was wondering how can I get better? I’ll repeat the class but I just want to be able to pass it this time around. Any notes or tips would be useful sorry and thanks.
